Pre-Ordering games from a different region on the Playstation Store?

I doubt It'll come as much of a surprise to learn that the game in question is Red Dead Redemption II.. I wouldn't mind saving a few quid if it's doable/relatively hassle free as it's $59.99 (£46.26) on the Usa PS4 store & £59.99 here in the UK for the same version of the game.

Can someone give me a heads up or point me somewhere.. thanks.
